Select OAK to the boxes to remove the discontinuity.
Entering a waypoint in the boxes which does not already exist on the route moves
the discontinuity one waypoint further down the route.
Direct To And Intercept Course To
If the airplane passes the last active route waypoint (or offset) or the last waypoint
prior to a route discontinuity, LNAV maintains the current heading. The EICAS
message FMC INTERCEPT HDG is displayed. If LNAV is not active, activation
can be accomplished in the following three ways:
• when the airplane is within 2.5 miles of the active leg and on an intercept
heading to the active leg, pushing the LNAV switch activates LNAV. The
airplane turns to intercept the active leg. If the intercept angle is large, the
airplane may overshoot the active leg
• when more than 2.5 miles from the active leg, pushing the LNAV switch
when the airplane is on an intercept heading to the active leg arms LNAV
and displays the intercept path on the ND map. Activation occurs as
necessary to intercept the active leg with no overshoot. The intercept
heading must intersect the active leg inbound before the active waypoint
• fly direct to a waypoint or intercept a course to a waypoint. Enter a
waypoint in the RTE LEGS page active waypoint line to fly direct. Use the
INTC CRS TO prompt in line 6R to create an intercept course to the
waypoint. Pushing the LNAV switch arms or activates LNAV, depending
on the distance to the active leg
The example below depicts the airplane being off course to the right, followed by
a modification to fly direct to BTG.
